During a policy review in 1996 into the handling of Unidentified Aerial Phenomena sighting reports received by the Ministry of Defence, a study was undertaken to determine the potential value, if any, of such reports to Defence Intelligence. Consistent with Ministry of Defence policy, the available data was studied principally to ascertain whether there is any evidence of a threat to the UK, and secondly, should the opportunity arise, to identify any potential military technologies of interest.

The Ministry of Defence has released this report in response to a Freedom of Information request and we are pleased to now make it available to a wider audience via the MOD Freedom of Information Publication Scheme. Where indicated information is withheld in accordance with Section 26 (Defence), Section 27 (International Relations) and Section 40 (Personal Information) of the Freedom of Information Act 2000.
